GENERAL DESCRIPTION

A-2

 

 

 

The CV Adapter consists of a capacitor bank, an elec- tronic control circuit and switches. The capacitors mod- ify the dynamic output characteristics to make the welder suitable for Innershield welding, and the elec- tronic circuit controls the field current to maintain a constant voltage output. Two switches are used to change from CV mode to VV mode. The switches are interlocked to insure that the capacitors are discon- nected before the Adapter can be switched to the VV mode.

All the components are installed in a control box that attaches to the welder gas tank rail with an adapter plate. A control cable is used to connect the CV Adapter to the welder control circuit and the output ter- minals. A power cable is used to connect the CV out- put terminal of the Adapter to the welder negative brushholder. This connection by-passes the series field for CV operation. A thermostat assembly is sent with the Adapter model for the SA-200 and SA-250 to pro- tect the welder if overloaded. Two thermostat assem- blies are included, one to be used with the SA-200 and one to be used with the SA-250. The assembly is field installed in series with the welder negative brushhold- er and the power cable. The chance of overloading the SAE machines is much less so no protection is provid- ed.

The operating schematic is L6922 and the wiring dia- grams are M14822 and M14726. The assembly is shown on G1643.
